Proteins are more difficult to digest than Amino Acids during exercise Proteins take longer to get absorbed than Amino Acids Proteins don’t taste very good during exercise Proteins can reduce the glycemic index of a drink, further reducing its ability to be quickly absorbed There is considerably more research that supports the benefits of Free Form Amino acids than complete proteins
Supplying fast and sustained energy for muscles Improved fluid absorption Reduced cramping and dehydration Improved performance Easy to digest and absorb Improved glycogen resynthesis Delayed central (mental) fatigue Replenish electrolyte loss.
